Parsimoni Joins Techstars' Autumn 2025 Programme!

We are thrilled to announce that our sister company, Parsimoni, is part of Techstars’ autumn 2025 space accelerator programme in Los Angeles! They are in great company, with 4 other very synergistic space startups ANT61, Azora, CISGAM, and Translunar Exports and Servicing Incorporated.

Kick off was on the 8th of September. For the next 3 months, Parsimoni will benefit from Techstars’ mentorship, network, and investment to drive their mission of making satellite-based resources accessible to all.

Parsimoni’s SpaceOS

Parsimoni is developing SpaceOS, a next-generation operating system tailored to satellites and their payloads. By using unikernel technology (see MirageOS for another example), the size of each application is optimised to its minimal viable state, reducing the attack size and improving performance. The resulting efficiency is valuable for users – reducing costs, extending mission capabilities, and allowing for more advanced processing in orbit – and also better for the planet. More efficient, multi-purpose satellites make better use of limited resources and create new possibilities for the satellite industry.

These advantages, along with its security-by-design approach (including PQC) and high adaptability to new features and applications, make SpaceOS the perfect candidate for use cases like AI-powered earth observation, secure mission operations, and next-generation space marketplaces.

Parsimoni uses OCaml to build their software, benefitting from the language's security guarantees, and this approach is garnering attention from a world-leading accelerator. It illustrates how Tarides' mission of building mission-critical systems in OCaml is a recipe for success – in the FinTech sector, space sector, and beyond!
